Pop star Taylor Swift is convinced she has never "truly" been in love because none of her romances have ever lasted.

The singer has been linked to a number of high profile men over the years, including John Mayer, Jake Gyllenhall and Taylor Lautner, and she is said to have recently split from Conor Kennedy.

Swift, who famously details her romances in her songs, now admits she has yet to experience true love.

She tells Parade magazine, "I tend to think things are love and then look back and reevaluate... I know how many people I've said 'I love you' to. I could probably count it up, but I don't feel like it. Part of me feels you can't say you were truly in love if it didn't last. If I end up getting married and having kids, that's when I'll know it's real - because it lasted."

Swift adds, "I don't think there's an option for me to fall in love slowly, or at medium speed. I either do or I don't.

"I don't think it through, really, which is a good thing and a bad thing. You don't look before you leap, which is like, 'Yay, this is awesome! Let's not think twice!' And then you're like, 'We used to be flying. Now we're falling. What's happening?'"
